Our Top Choice

KIDADL TOP PICK

Kids' Inflatable Rex Toy Story Costume - Fancydress.com‍

Kids' Inflatable Rex Toy Story Costume.

When it comes to Halloween costume ideas, there are so many to choose from. They also tend to be gendered, which can make it a challenge to choose a top pick that will work across the board. This costume does just that. It's an investment, but it's worth it - what kid won't love waddling around as Rex from Toy Story? Plus, this is one of the Halloween costume ideas that gets most points for hilarity, thanks to its inflatable nature. Even better, it can be re-used for birthday and fancy dress parties - or just for bumbling around the house and treating everyone to a good giggle. The bodysuit is zip up and has a battery-powered fan which inflates the costume via four AA batteries.
